Floribunda rose plant named &#39;Meickinava&#39;

ABSTRACT

A new and distinct Floribunda rose plant is provided that forms on a substantially continuous basis blossoms having an intense deep red coloration. The growth habit is bushy with the formation of strong vegetation. The vegetation is very dense and bears a glossy aspect on the upper surface. The plant has been found to grow well on its own roots. No particular disease problem has been observed. The plant is particularly well suited for providing attractive ornamentation in parks and gardens.

BOTANICAL/COMMERCIAL CLASSIFICATION

Rosa hybrida/Floribunda Rose Plant

VARIETAL DENOMINATION

cv. Meichinava

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Hybrid Tea rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the ‘Noacas’ variety (non-patented in the United States). The male parent (i.e., the pollen parent) was an unnamed and unreleased seedling (non-patented in the United States).

The parentage of the new variety can be summarized as follows:

‘Noacas’×Unnamed Seedling.

The seeds resulting from the above pollination were sown and small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new Floribunda rose plant of the present invention:

(a) displays a bushy growth habit with strong vegetation,

(b) forms in abundance on a substantially continuous basis attractive single blossoms having an intense deep red coloration,

(c) grows well on its own roots,

(d) exhibits attractive dense glossy dark green foliage, and

(e) is particularly well suited for providing attractive distinctive ornamentation in parks and gardens.

The blooming tends to commence medium in the season, during observations to date. The blossoms display a distinctive forceful deep red coloration that contrasts nicely with the coloration of the foliage.

The new variety well meets the needs of the horticultural industry and can be grown to advantage where attractive ornamentation is to be provided.

The new variety can be readily distinguished from other Foribunda rose varieties. For instance, the ‘Noacas’ parental variety forms dissimilarly colored orange to orange-red blossoms combined with a more spreading growth habit.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and the use of cuttings. Asexual propagation by the above-mentioned techniques at Le Cannet des Maures, Var, France, has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner. The plant grows well on its own roots.

The new variety has been named ‘Meickinava’.

BRIEF DESCRIPTION OF PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were approximately two years of age and were observed during June while growing outdoors on their own roots at Le Cannet des Maures, Var, France. Comparative standard color information is included at the base of the photograph.
